Urology – MESA/TESE

MESA/TESE Surgical sperm collection

If there are no sperms in the seminal fluid (AZOOSPERMIE), they can be extracted from the testicles or epididymides by microsurgery:

• MESA – Micro Epididymal Sperm Aspiration – Suction of sperm from the epididymides
• TESE – Testicular Sperm Extraction – testicular tissue extraction, which is then processed in the laboratory – the collected sperm is used to fertilise oocytes using the ICSI method.

The urological operation MESA/TESE is one of the methods of artificial insemination in the treatment of male sterility, and is used when there are no sperm in the seminal fluid, but all the prerequisites for their formation in the testicles are given (e.g. in the case of a transport disorder of the sperm). The biological material is extracted from the epididymis (MESA) and tissue is removed from the testicles (TESE). The sperm are then used to fertilise the oocytes during IVF. The procedure is performed under full or spinal anaesthesia.
